It is possible, however, that in practice some types of aerospace object will be considered aircraft even if they perform parts of their flights in outer space and other types of aerospace object will be considered essentially space objects because they use some elements of aerodynamics only for the purpose of take-off from and landing on Earth.
Considerando que la finalidad de un objeto aeroespacial es incursionar en el espacio exterior, sin perjuicio de su capacidad funcional que le permite comportarse como una aeronave en ciertas fases de su navegación, es preferible que se aplique un régimen uniforme a todos estos objetos.
